It will be noticed "thatFin the preferred illustration shown on thedrawings, the scoring' roller 29' is"provided with' two dies'aa upon itscylindrical face, which means that two can ends will'be scored in. thecourse of 0. 36 revolution ofthe'shaft 28 and the scoring however; thatany of the scoring and feedingroller: 29,, such number dependingjuponthe-rel'ative size'ot the scoring roller "and the 'can' end.' 7
